<p>And then there are us engineers. I don't care much either way whether Maxwell's equations are ∇F = J or some other form, as long as it makes the problem easier to solve.<p>If I were in the GA Marketing Committee I'd publish a paper with suitably hand-picked worked examples where the vector approach is long and tedious, and GA version is short and sweet.</p>

<p>They're not great for anything that might produce heat. Seeing a MOSFET slowly starting to imitate the Tower of Pisa after dissipating a measly 1 W for a few moments was a sight to behold.<p>For about two seconds before I cut the power.</p>

<p>One of these years I'm going to make a Finnish programming language that enforces the correct case in arguments. And I don't mean silly arguments like camelCase vs kebab-case, I mean grammar.<p>Some examples to illustrate:<p><pre><code>  tiedosto on "foo.txt" avattuna
  tulostin on PRN1
  kirjoita(tiedostoon, "a")
  kirjoita(tulostimelle, "b")
</code></pre>
Job security for DECADES.</p>

<p>If there were one. The closest thing is the Treaty of Lisbon, which in turn was an update on the Treaties of Maastricht and Rome.<p>However, the matter has been heard in the European Court of Justice in 2002, and the short version is "Community law does not preclude compulsory military service being reserved to men."<p>For more details, feel free to study the legal opinion behind the ruling: <a href="https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:62001CC0186" rel="nofollow">https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CEL...</a></p>

<p>Humbug. Defence policy, especially how the EU member states choose to organize their military forces, is very much in the hands of the individual countries. A majority of the member states don't even have conscription anymore.<p>Yes, there is the common security and defence policy, and the Article 42 of Lisbon and all that, but it all still relies on national systems.</p>

<p>Most of economics is educated guessing, and having more data (hopefully) leads to better guesses.<p>With this study there's plenty of leads to follow. Does the ABV have an impact? What about the base price? France vs Italy?</p>

<p>I couldn't let this be, so I went through the commits and as far as I can tell, that's the case. The committer/author names and timestamps are consistent with using --author on a commit (... or in a few cases, --amend --author).<p>Except one: commit 3d1fdddf9 has Jia Tan as both author and committer but the author timestamp is in +0300 while the commit timestamp is +0800.</p>

<p>UTC+2 isn't very convincing as an argument for Russia. Only the Kaliningrad exclave uses that timezone, and if I were in a state-backed group, I'd live in one of the big cities.<p>Also quick search suggested UTC+3 was seen during the summer, and Russia doesn't do DST either.<p>Edit: some of the UTC+2/3 times are attributable to being differences in git committer and author dates (e.g. email patches)</p>

<p>For most of Great Britain, the grid north differs from true north because the grid cells are fixed size, so they "fan out" compared to longitude lines. The exception is the 2°W meridian where the grid lines up.<p>The magnetic north wanders around, and it now happens to match along the 2° meridian.<p>But really the article is a year early, as the alignment point should make a brief landfall in Scotland late next year (which the article acknowledges later on). Or perhaps they expect Scotland to secede before that.</p>

<p>It's Juice (Jupiter Icy Moons Explorer) and it's not yet anywhere near Jupiter. Its trajectory has a few slingshot loops around Venus and Earth, and it's just coming off the Venus encounter.<p>It's about 0.43 AU from the comet at its nearest, whereas Earth will be pretty much on the opposite side of the Sun, making observations difficult from here.<p>Edit: Earth, Mars and Jupiter are in roughly 120 degrees from each other as seen from the Sun, with the Earth-Sun-Jupiter angle closing up fast and the E-S-M angle growing slightly slower. In about two months the E-S-M angle will be 180.</p>
